Comparative Study of Torque Ripple Minimization of PMSM using PI and Proportional Resonant (PI-RES) ControllerBy Karthika S, Vishnu Mahesh J
Abstract: The minimization of speed ripple of the permanent magnet synchronous motors (PMSM) in low speed range becomes a major problem while applying the PMSM to refrigerant system. Earlier, an iterative learning controller was applied in conjunction with the conventional proportional integral (PI) speed controller to minimize the speed ripple. Here, a frequency variable resonance controller is applied in conjunction with the conventional proportional integral speed controller as a PI-RES controller, …
